Example Embodiment
[0050] Example 1
[0051] 1) Use scrap steel, ferrosilicon, ferromanganese, ferrosilicon, ferromolybdenum, ferrochrome, ferro-titanium, ferrovanadium, ferro-niobium, and rare earth silicon as raw materials for smelting, and do the ingredients according to the following components: C: 0.25 wt.%;
[0052] Si: 0.9 wt.%;
[0053] Mn: 0.3 wt.%;
[0054] Cr: 0.7 wt.%;
[0055] Mo: 0.15 wt.%;
[0056] Ti: 0.05 wt.%;
[0057] Nb: 0.01 wt.%;
[0058] V: 0.05 wt.%;
[0059] RE: 0.01 wt.%;
[0060] P, S≤0.01 wt.%
[0061] The rest is Fe and inevitable impurities;
[0062] 2) Use an intermediate frequency induction electric furnace for smelting. Firstly, ordinary scrap steel and ferrochrome are mixed by heating and melting, and the furnace is analyzed;
[0063] 3) Add ferromanganese, ferrosilicon, and ferromolybdenum in turn, wait for all to be melted, then add ferrochrome, and then further melt, deoxidize with aluminum wire, and then flush the molten steel into and place ferro-titanium, ferro-vanadium, fe...
